Capacitors; Reforming The Capacitors; Control Panel; Cleaning The Control Panel - ABB ACS880-34 Series Hardware Manual

Capacitors

The DC link of the drive contains several electrolytic capacitors. Operating time, load, and
surrounding air temperature have an effect on the life of the capacitors. Capacitor life can
be extended by decreasing the surrounding air temperature.
Capacitor failure is usually followed by damage to the unit and an input cable fuse failure,
or a fault trip. If you think that any capacitors in the drive have failed, contact ABB.
￭

Reforming the capacitors

The capacitors must be reformed if the drive has not been powered (either in storage or
unused) for a year or more. The manufacturing date is on the type designation label. For
information on reforming the capacitors, see Capacitor reforming instructions (3BFE64059629
[English]) in the ABB Library (https://library.abb.com/en).

Control panel

For detailed information on the control panel, see ACx-AP-x assistant control panels user's
manual (3AUA0000085685 [English]).
￭

Cleaning the control panel

Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch
the display window.

Replacing the control panel battery

For instructions on how to replace the control panel battery, see ACx-AP-x assistant control
panels user's manual (3AUA0000085685 [English]).
